Containment of produce

ABSTRACT

A partition, which has a perforate body part ( 1 ) and radially extending ligulate projections ( 5,6 ) around the body, with preferably a peripheral ring ( 27 ) joining the distal ends of the ligulate projections. The partition may be flat or cup shaped and is used in the field of containment of produce, in particular where produce is contained in a closed container immersed in a liquid. A primary example of an application of the invention is in containment of natural produce such as fruit and vegetables.

FIELD OF THE INVENTION

This invention lies in the field of containment of produce, in particular where produce is contained in a closed container with a liquid, preferably to be immersed in the liquid. Although a primary example of an application of the invention is in natural produce such as fruit and vegetables, the invention can be applied in the containment of a wider range of produce in the sense of any product of some or other activity. As another example of a possibility, the invention may be applied to containment of items that should not rattle or fall around or be loose in a bottle. Products like medicinal or food supplement pills may be in this category and there are many other potential applications.

BACKGROUND

Natural produce such as fruits and certain vegetables are often preserved and marketed in bottles in a liquid, which preserves, pickles, flavours, colours or otherwise affects the produce. Sometimes a part of the contained produce deteriorates by discolouring, loss of flavour, drying out to an extent or in other ways. This is often due to the produce not being fully covered or floating with a portion of it above the liquid surface.

THE INVENTION

This invention provides a partition, which comprises a perforate body part and radially extending ligulate projections around the body.

Preferably there is a peripheral ring joining the distal ends of the ligulate projections.

The partition may be a plate or disc, i.e. essentially flat and thin relative to its transverse dimension or diameter. A disc would be suitable for a round container, such as a round bottle or can, whereas a plate may be suitable for a square container, for example.

The partition may alternatively have a cup shape, i.e. the projections would extend initially in a flat or disc-like shape, so forming a base part of a cup shape, then turn upwards, so forming the walls part of a cup shape.

An intermediate ring may be provided at the position where the projections turn up from the base part t the walls part.

The projections preferably are adapted by their thickness and/or material properties to exhibit elasticity so as to provide sprung portions, as may be useful to take up space in an elastic way. This may be useful to provide a partition that lightly presses against product in a container, with some degree of automatic compensation for differing levels of filling of the container.

The ligulate projections may include longer radial projections alternately interdigitated by shorter projections, the latter spanning a transverse dimension or diameter of a container or container neck. The projections may be adapted or suitable to be bent when the partition is inserted into a container above its contents, so as to wedge or locate the partition in the container or against the cap, lid or other closure means of the container. The projections may act against a roughened or serrated interior surface of the container.

The perforation of the partition body may be specifically adapted to interact with a filling means by which the container is filled with a liquid. The body may thus have a rim, ring or other peripheral formation to interact with a filler tube or nozzle. The intermediate ring may be dimensioned and positioned to interact with a filler tube or nozzle.

However, the partition may alternatively for particular applications have substantial thickness, for example easily compressible like a sponge or sprung portions, as may be useful to take up space in an elastic way. This may be useful to provide a partition that lightly presses against product in a container, with some degree of automatic compensation for differing levels of filling of the container.

The body of the partition may have a means of holding and releasing the partition by a mechanical device, to facilitate mechanised insertion of the partition into a container. For example, the body may have a smooth surface area, preferably in the centre of the body, where a suction type holder may hold the partition for insertion into a container, e.g. the neck of a bottle.

THE DRAWINGS

The invention is more fully described by way of non-limiting examples, with reference to the drawings, in which:—

FIG. 1 is a plan view of a partition according to a first preferred embodiment,

FIG. 2 is a cross sectional elevation of the partition on section II-II shown in FIG. 1,

FIG. 3 is a cross sectional elevation of the partition, a bottle insertion and filling means and a bottle, preparatory to inserting the partition,

FIG. 4 is a cross sectional elevation of the partition inserted into a bottle,

FIG. 5 is a plan view of the partition according to a second preferred embodiment, and

FIG. 6 is an elevation of the partition shown in FIG. 5.

THE PREFERRED EMBODIMENT

As shown in FIGS. 1 and 2, the partition 1 is a disc comprising a circular flat body part 2 perforated by apertures 3 and radially extending ligulate projections 4 and 5. The projections 4 are longer than the projections 5 and the latter are alternately interdigitated between the former. The diameter 6 across the shorter projections 5 is equal to the internal diameter 7 of a bottle 14 and the diameter 8 across the body of the partition is equal to or smaller than the diameter 9 of the neck 15 of the bottle (see also FIG. 3). The diameter 10 across the longer projections 4 is appreciably larger than the diameter of the neck of the bottle and the length 11 that each longer projection projects beyond the body is equal to the distance 12 that it is required for the partition to be held below the bottle cap 13 (see FIG. 4). There is a split or cut 19 going partially through the proximal end of each projection where it joins the body of the partition, to provide a hinging action of the projections when the partition is inserted into the bottle. An elastic effect causes the projections to spring back if permitted, after being hinged.

FIG. 3 shows the partition located above the bottle preparatory to being inserted by a rod 16 which will hold the partition by means of a suction cup 17. A filler tube 18 is also located above the bottle preparatory to being lowered into the bottle neck to fill the bottle up to a desired level with a liquid.

FIG. 4 shows the partition placed into the bottle, located below the bottle neck by means of the shorter projections bearing against the shoulder of the bottle where its diameter reduces to the neck of the bottle. The longer projections bear against the bottle cap to further ensure that the partition remains in this position while the cap is on. When the cap is removed for use, the partition may be lifted out to allow removal of the produce in the bottle.

As shown in FIGS. 5 and 6, the partition 21 is a disc comprising a circular flat body part 22 perforated by apertures 23 and radially extending ligulate projections 24. The projections 24 extend beyond an intermediate ring 25 upwardly as at 26, thus forming the base part 28 and side walls part 29 of a cup-like shape. A ring 27 terminates the distal ends 30 of the projections 24-26.

The partition is dimensioned to fit into the neck region of a bottle, the ring 27 to be located against the bottle cap and the base part against produce or loose articles (like pills) kept in the bottle.

The partition may be used in a bottle in much the same way as shown in FIGS. 3 and 4.

The projections can be bent, conferring some compressibility or elasticity to the partition, so as to serve the function required of it.
